I have a confession to make.
Watching someone unknowingly walk straight into a glass door or window is the MOST hilarious thing ever.
It makes me laugh loud and uncontrollably (just ask the hubs).
For awhile our local movie theatre had a preview for a phone company that had someone walking into the store front window that had me almost pee my pants every. single. time.
Below, you can watch Justin Bieber do it not once... but TWICE.
